본 논문은 실내 공간구획에 사용되는 경량칸막이 복합벽체의 가열온도에 따른 이면부로의 전도 열전달 특성에 관한 연구이다. 경량칸막이 벽체로 일반적으로 사용되고 있는 복합재료로 구성된 스터드 칸막이, SGP 칸막이, 샌드위치 패널, 우레탄폼 패널, 그라스울 패널을 실험시료로 선정하고, $200^{circ}C$, $300^{circ}C$, $400^{circ}C$, $500^{circ}C$의 가열온도를 하단부 표면에 1800 s 동안 인가하여 상단부 표면인 이면부로의 전도 열전달 특성을 분석하였다. 실험결과 가열온도가 최대 $500^{circ}C$로 인가됨에 따라 최대 이면온도는 스터드 칸막이 $51.6^{circ}C$, SGP 칸막이 $63.6^{circ}C$, 샌드위치 패널 $317.2^{circ}C$, 우레탄폼 패널 $124.9^{circ}C$, 그라스울 패널 $42.2^{circ}C$로 측정되었다. $500^{circ}C$에서의 최대 전도 열전달율은 스터드 칸막이 17.16 W, SGP 칸막이 18.39 W, 샌드위치 패널 136.65 W, 우레탄폼 패널 14.34 W, 그라스울 패널 5.57 W로 측정되었다. |

The paper reports the characteristics of conduction heat transfer to the backside part according to the heating temperature of a composite wall in a lightweight partition used for indoor space compartments. Stud partitions, SGP partitions, sandwich panels, urethane foam panels, and glass wool panels. which are generally used as light-weight partition walls, were selected as experiment samples, and the characteristics of conduction heat transfer to the backside part as the top surface were analyzed by applying heating temperatures of $200^{circ}C$, $300^{circ}C$, $400^{circ}C$, and $500^{circ}C$ to the bottom surface for 1800 s. According to the experimental results, the maximum backside temperatures at the maximum heating temperature of $500^{circ}C$ was $51.6^{circ}C$, $63.6^{circ}C$, $317.2^{circ}C$, $124.9^{circ}C$, and $42.2^{circ}C$ for the stud partition, SGP partition, sandwich panel, urethane foam panel, and glass wool panel, respectively. The maximum conduction heat- transfer rates at $500^{circ}C$ were 17.16 W, 18.39 W, 136.65 W, 14.34 W, and 5.57 W for the stud partition, SGP partition, sandwich panel, urethane foam, and glass wool panel, respectively. |
